WINDOW SASH 0R FRAME.

Application filed November 15, 1911.

To all witom it may concern;

Be it known that I, MAURICE a citizen of the United States, of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Window Sashes or Frames, of which the following is a specification.

My present invent-ion relates to the construction of window sashes.

The object of the invention is to simplify and cheapen the construction of metal window sashes and to obtain a completed sash the members of which will be effectively locked together and which will present a neat symmetrical appearance.

Another object is to attain an improved construction by which the sash can be shipped knock-clown and then be readily assembled at the place of installation.

he invention is primarily intended for application to the manufacture of hollow sheet metal sashes and is illustrated herein as applied to such type of sash but it will be understood that the application of the invention is not limited thereto as it might equally well be employed in the construction of other styles of sashes as for instance one in which the members are made of solid metal.

The invention consists in the improved construction of metal. window sashes hereinafter more particularly described and then specified in the claims.

In the accompanying drawings, l igure '1 is a perspective view illustrating the various parts of one form of window sash constructed for being assembled in accordance with this invention.

Fig. 2 is a perspective view of the completed sash.

Fig. 3 is a perspective view of the foundation for the window sash and illustrates the first step in the process of assembling the sash.

Fig. -1- is a transverse section through one of the members of the preferred form of sash.

Fig. 5 is a similar view of a modified construction of member.

In accordance with this invention the crossed munnions forming the sash or frame comprise a set of inner or foundation members and outer or molding members all inter- LACHMAN, and a resident Specification of Letters Patent.

locked with each other locked structure.

Preferably a complete foundation for the window sash is first constructed, irrespective of the number of panels embodied in the complete framework, after which the molding members are applied to the foundation and then secured to the foundation, the molding members being so formed and organized that, without the necessity of any other means than those that secure the molding to the sash they are effectively locked to each other and any relative displacement of them is prevented.

The foundation comprises a set of members l of any desired length and number and which are spaced apart the desired distance according to the size panel desired and a: second set of members 2 similar in form to the members 1, and. arranged to intersect said members at any desired point. When made of sheet metal, each member is bent into substantial U-shape in cross-section, the free edges of the U being each provided with longitudinal laterally projecting flanges 3, 4, whereby the entire member as a whole is T-shaped in cross-section. The flanges of each member of one set, as for instance 1, are preferably continuous and each member of such set is provided with a slot 5 entering the member from the base of the U and located at each point where it is desired that the sash shall intersect. The flanges of the cooperating illoundation members 52 are each cut away as at .6 to receive the flanges of the members I. and a slot 7 is tlornied in the members 2 entering from the top of said member. at each point of desired intersection so that when the members 1 are placed to intersect the members 2, the solid part of the members 1 will enter the slot 7 of the members 2 and the flanges 8, i of the members 1 will rest in the cut away portions 6, thus bringing the flanges 3, 4!- of all members in the same plane. and completiugthe foundation framework. Y

8 indicates the members of one set of moldings. The members might be formed with any desired character of molding and each is provided with a longitudinal de pending flange 9 along each edge. Each flange 9 is cut away at 10 to permit the flange to pass down beyond the edges of the flanges 3, 4 of the members 2 when the moldto form an effective in the same plane,

bulges in the depressions 11 centrally located above the in the center cuts 10 or, in other words,

molding of the desired intersection of the members. 12 indicate the members of ing set of molding members, the molding formed on each member being the same as that formed on the members 8. Each member, as in the case of the members 8, is pro vided with a pair of depending side flanges 13. The side flanges 13 and part of the molding is 'cut away on each side of the longitudinal center at a number of points 1 1- so that the members 12 can be placed to intersect the members 8, and can be forced down until the top surface of the molding of the members 8 and 12 are flush and lie the central continuous portion of the members13 entering the notches or depressions 11 in the members 8. When the foundation members 1, 2 have been placed as shown in Fig. 3, the molding members 8 are placed on the members 1, and the members 12 are placed over the foundation members 2 and intersecting the members 8, the flanges 9 and 13 project down along the edges of the foundation flanges 3, 4:. The said flanges 9 and 13 are then turned or folded under the flanges 3 and 1 of the members 1 and 2 as shown in Figs. 2 and 1, and the molding members are fastened to the foundation and the sash members as a whole are locked against independent relative movement in. any direction, movement in one lateral direction being prevented by the metal below the slots ,7 and in the opposite lateral direction by the continuous metal or the members 12.

By referring to Fig. 2 the uniform, clean cut and symmetrical aprmaranco of the sash will be observed, the members being effectively locked to each other without any metal at the joint.

Preferably, the sash is made hollow and of sheet metal as by so doing the various cut away portions can be readily punched out before the members are bent into shape, but it will be understood that the members may be formed or rolled of solid metal shapes having the necessary flanges for securing them together without departing bead at the top of Copies of this patent may be obtained for the cooperatbeing shown in Fig. 5.

from the invention in 'so. far as it relates to the process of assembling: the various members into a completed structure.

Also the invention is not limited to any particular style or character of molding nor to the specific manner of locking the molding to the foundation heretofore described, another manner of locking the parts In this form the foundation .members 1, 2 are merely U shaped in cross-section without the projecting flanges 8, 4: of the prior form. The depending flangesof the molding members in this case are brought farther in toward thecenter and into'such position that they engage sidewise with the opposite sides of the foundation members. then be secured to the foundation by welding, riveting or in any suitable manner.

What I claim as my invention is:

1. A metal sash or frame comprising T- shaped intersecting foundation members and continuous molding members intersect- The flanges may ing each otherand superimposed on and secured to said foundation members, one of said molding members provided with an opening in its upper portion through which a portion of the other molding member passes at the intersecting point.

2. A metal sash or frame comprising T- shaped intersecting foundation members, continuous molding members superimposed on said foundation members and secured to the flanges thereof, one of said molding members being provided with a slot in its upper surface and a head on the other molding member located in said slot at the point of intersection whereby the molding members are continuous and all parts lie in the same plane.

3.1n a fireproof Window sash, crossed munnions, consisting of inner members secured together and outer members secured to the inner members, one of the outer members having an opening at the crossing point and the 7 other outer member extending through said opening.

Signed at New York, in the county of New York and State of New York this 13th day of November, A. 'D. 1911.
